Which? Car Survey 2011

The Which? Car Survey is a chance for real buyers to say what they love or hate about the cars they own.

The feedback we received in the 2010 Which? Car Survey meant ours was the UK’s biggest survey of car reliability and satisfaction for the fourth year running.

It will take between 10-20 minutes to fill in, and anyone who takes part can choose to be entered into the draw to win £5,000.

Carmakers pay close attention to our survey results, and we use what we find ou to push manufacturers to drive up standards in the motoring industry.

Here are the most reliable superminis from the 2010 Which? Car Survey results.

New superminis

Kia Picanto

Kia Picanto

1. Kia Picanto

Model year: 2004-

Reliability score: 98%

Although it’s cheap to buy, that didn’t stop the Kia Picanto from being voted the most reliable new supermini of 2010. The petrol-only Picanto received top marks for its lack of breakdowns, faults and niggles. There will be a new Picanto in 2011, replacing this long-running version. 

Daihatsu Sirion

Daihatsu Sirion

2. Daihatsu Sirion

Model year: 2005-

Reliability score: 97%

The Daihatsu Sirion is closely related to the Toyota Yaris, so reliability was always expected to be high. It scored well in our survey for reliability, taking into account all three petrol engines (1.0-litre three-cylinder, 1.3 and 1.5), but marginally lost out to the Kia Picanto.

Honda Jazz

Honda Jazz

3. Honda Jazz

Model year: 2008-

Reliability score: 96%

The Honda Jazz in its latest guise became available in January 2009. It’s always been a high scorer in our survey, and it accomplished the same again in 2010, receiving top marks for breakdowns, faults and niggles. There are no diesel options for the Jazz, so the results are specifically for petrol cars only. Honda reliability as a manufacturer is extremely high.

Toyota iQ

Toyota iQ

4. Toyota iQ

Model year: 2008-

Reliability score: 96%

The Toyota iQ is more of a city car than a supermini, but it still scored top marks in our 2010 survey from those who bought the car new. The super-small iQ is less than three-metres long, but it received top feedback for reliability for both the 1.0 and 1.33-litre petrol options.

Mazda 2

Mazda 2

5. Mazda 2

Model year: 2003-2007

Reliability score: 93%

The Mazda 2 is the sister model to the Ford Fiesta, although this previous generation model looks quite different. It’s economical, practical and easy to look after. The Which? Car Survey 2010 results showed top marks for its lack of faults and niggles, but it was a slightly let down by the number of breakdowns. The scores were the same for petrol and diesel versions.

Used superminis

Toyota Aygo

Toyota Aygo

1. Toyota Aygo

Model year: 2005-

Reliability score: 88%

Toyota is a manufacturer with a strong reputation for building reliable cars, and the Aygo supermini is no exception. According to our Which? Car Survey 2010 results, the breakdown numbers for the Toyota Aygo are low. However, niggles and faults can occur from time to time.

Peugeot 107

Peugeot 107

2. Peugeot 107

Model year: 2005-

Reliability score: 87%

It’s no surprise the Peugeot 107 has scored so closely to the Toyota Aygo – the two cars, along with the Citroen C1, are built in the same factory. Peugeot isn’t recognised as the most reliable carmaker, but the 107 has bucked this trend with a strong score.

Honda Jazz

Honda Jazz

3. Honda Jazz

Model year: 2002-2008

Reliability score: 87%

Not quite as good as the reliability score when buying new, the practical and versatile Honda Jazz scores respectable marks from motorists who’ve bought the car second-hand. Because it is held in such high regard, the Honda Jazz holds its value well on the used market.

Kia Picanto

Kia Picanto

4. Kia Picanto

Model year: 2004-

Reliability score: 86%

According to the Which? Car Survey 2010, the Kia Picanto was the most reliable new supermini last year. And it appears the same car scores well with second-hand owners too, receiving a respectable 86%. It doesn’t score quite so well for safety, however.

Daihatsu Sirion

Daihatsu Sirion

5. Daihatsu Sirion

Model year: 2005-

Reliability score: 85%

The Daihatsu Sirion was rated well for reliability from new and it retains good reliability scores from used buyers. It’s cheaper to buy used than its sister car, the Toyota Yaris, and you could still benefit from the five-year warranty that end-of-line cars came with.
